Sub-family EvHEostoMaTIn®, (Tue Darters.) 
Genus 7. Micrererca, Putnam. 
9. Microperca punctulata, Putnam.—Leasr Darrer. 
This little species, the smallest of our fishes, is much the com 
monest northward, but has been taken as far south as Union county 
It is less select in its haunts than most of the other Darters, o¢ 
curring in waters of every description; but we have found it com. 
monest in lakes, and scarcely less abundant along the weedy mar. 
gins of larger rivers. 
Genus 8. HrxHrostoma, Raf. 
10. Htheostoma eos, Jor. & Copeland. 
(Bul. Il, 42; Boleichthys eos: Synop., Peecilichthys eos.) 
Not especially common in Illinois; chiefly of northern distribution ; 
most abundant in lakes, and occurring also in the smaller rivers. 
11. Htheostoma fusiforme, Grd. 
(Bul, II, 48; Boleichthys elegans: Synop., 519 & 520; Peecilichthys 
butlerianus, Pecilichthys barratti, Pecilichthys fusiformis.) - 
This darter, which has appeared in the earlier lists as Boleichthy 
elega:s, is southern in its Illinois distribution, not having occurred 
north of the Kaskaskia River. To the southward it is rather com- 
mon in lakes, clear ponds, small rivers and creeks. 
12. Htheostoma asprigene, Forbes. 
(Bul. II, 41; Peecilichthys asprigenis: Synop., pL 06.) 
This common species, originally described from the Illinois River, 
has since been found generally distributed in the central and south- 
ern parts of the State, in lakes and rivers, large and small, but has 
not been taken in Northern Illinois. | 
13. LHtheostoma ceruleum, Storer.—Buur Darter; Ratnpow Darter; 
SOLDIER-FISH. 
(Bul. II, 41; Pweilichthys variatus, Pecilichthys  spectabilis : 
Synop., 517 & 518; Peecilichthys coeruleus, Peecilhiehthys spec- 
tabilis.) 
The most highly colored of our common darters, occurring 
throughout the State in lakes, rivers and creeks, much the most 
abundant in the latter. pate | 
14. Htheostoma flabellare, Raf. 
Not common. Clear creeks and rivers in Southern Illinois.
